Sodium Cocoamphoacetate
Ingredient Info
Sodium cocoamphoacetate is a mild surfactant derived from coconut oil that helps cleanse skin by removing dirt and oil. It's commonly used in gentle cleansers and makeup removers because it's less harsh than traditional soap-based surfactants.
Benefits
- Effective at removing makeup and impurities
- Gentler than stronger surfactants like sodium lauryl sulfate
- Well-tolerated by most skin types, including sensitive skin
Potential concerns
- Can cause mild irritation at higher concentrations (10%+), though typically at lower irritation levels than harsher surfactants
- Rare contact allergy reported in isolated cases
- May cause dryness or transepidermal water loss with prolonged or repeated exposure at high concentrations
Science: Research shows sodium cocoamphoacetate induces lower irritation compared to stronger surfactants like sodium lauryl sulfate and benzalkonium chloride. Patch testing studies indicate it causes minimal irritant responses even in people with pre-existing dermatitis, eczema, or atopic conditions, supporting its use as a gentle cleanser ingredient.
